Application Dilution
Western Blotting 1:1000

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

NALP1 Antibody detects endogenous levels of total NALP1 protein. This antibody also detects a 70 kDa protein that correlates with a predicted short form (NALP1s) that lacks the leucine repeat region (7).

Species Reactivity:

Human, Mouse, Rat

Species predicted to react based on 100% sequence homology

Monkey

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide that corresponds to a region surrounding Gly1081 of human NALP1 protein. Antibodies were purified by peptide affinity chromatography.

Background

NALP1 (DEFCAP/NAC/CARD7) is an NLR (Nod-like receptor) family member that has been implicated in the regulation of apoptosis and inflammatory responses (1-5). Structurally, NALP contains an amino-terminal PYRIN domain, followed by a nucleotide-binding site (NBS), a leucine-rich repeat region (LRR), and a carboxy-terminal CARD domain. NALP1 interacts strongly with caspase-2 and weakly with caspase-9, and induces apoptosis when overexpressed (3). Similar to a related Ced-4 family member Apaf-1, it was also shown to be involved in cytochrome c-dependent caspase activation (2). It has also been shown to be part of the "inflammasome" comprised of caspase-1, caspase-5, and Pycard/ASC, which is critical in the processing of pro-inflammatory cytokines like IL-1β (6). Two major isoforms were identified for NALP1, which differ in a 44 amino acid region within the LRR (3). In addition, like NALP3, a short NALP1 isoform lacking the LRR (NALP1s) likely exists (7). Polymorphisms in NALP1 have been associated with autoimmune diseases (8) and susceptibility to toxins (9).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
